Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in figures 1-2, a coating roller with single side polishing comprises a horizontal inner shaft core 1, an outer roller body 2 and a rotating motor, wherein the cylindrical inner shaft core 1 is vertically and convexly arranged at the centers of two ends of the outer roller body 2, in the rotary roller type coating process, an outer roller body 2 needs to be driven by a rotary motor, an inner shaft core 1 is rotatably arranged on a coating machine, an anilox area 2a and a polishing area 2b are arranged on the outer edge surface of the outer roller body 2 in a surrounding way, the polishing area 2b is positioned on one side close to the rotary motor, when the outer roller body 2 rotates, the textured area 2a is brought up and temporarily stores a coating liquid including various types of glues and the like, which is then transferred to the surface of the substrate to be coated flat at a certain rate, the polishing area 2b has a smooth surface and is not easy to be stained with the coating liquid in the contact process with the coating liquid, so that the surface is always kept in a liquid-free state, and the part of the substrate which does not need to be coated with the coating liquid can not be polluted reversely.

Because the functional area for realizing coating is the textured area 2a, and the polishing area 2b is arranged for preventing the coating liquid on the edge from sticking on the roller, the coverage area of the textured area 2a is far larger than that of the polishing area 2b, the axial length range of the polishing area 2b is 80-120 mm, the length is reasonable, and the coating machine is suitable for various coating machines; the surface roughness Ra of the polished polishing area 2b is less than or equal to 0.2 mu m, the surface roughness refers to the unevenness of small intervals and micro peaks and valleys on the processed surface, the distance (wave distance) between two peaks or two valleys is small, the micro geometrical shape error is contained, and the smaller the surface roughness of the object is, the smoother the surface is; regular mesh point holes 3 are uniformly distributed on the surface of the reticulate pattern area 2a, the surface roughness of the mesh point holes 3 is high, and the mesh point holes are used for being stained with masking liquid and realizing uniform and stable liquid feeding; the thickness of the polished section 2b is reduced so that the outer peripheral surface thereof is located within the outer peripheral surface of the textured section 2 a.

The diameter of the inner shaft core 1 is smaller than that of the outer roller body 2, the outer roller body 2 is of a hollow tubular structure with two closed ends, the design is light, materials are saved, the weight of the whole machine is effectively reduced, and more importantly, the load of a unit for driving the outer roller body to work is also reduced, so that the energy consumption is reduced; the center shaft centers of the inner shaft core 1 and the outer roller body 2 are overlapped and fixedly connected in a welding mode, the connection is firm, machining processing can still be carried out after the connection, the coaxiality of the inner shaft core and the outer roller body is guaranteed, and rotation jumping during working is reduced.

The driving shaft of the rotating motor is connected with the inner shaft core 1 and then connected with the outer roller body 2, and a speed change device is arranged between the rotating motor and the inner shaft core 1, so that the coating speed is convenient to adjust, continuous coating or intermittent coating can be carried out, and the coating quality is further improved.

The inner shaft core 1 and the outer roller body 2 are both made of 45# steel or alloy steel, and both have high strength and deformation resistance, so that the middle section of the roller body is not bent to influence smooth coating; specifically, the outer roller body 2 is made of a national standard thickened seamless steel pipe, the whole body of the outer roller body is seamless, cracks can not be generated even if the outer roller body is in contact with coating liquid for a long time, the coating liquid is effectively prevented from leaking into the roller body, the reticulate pattern area 2a on the surface of the outer roller body 2 is formed by extrusion, and the processing technology is mature and convenient; the inner shaft core 1 is a solid cylinder, and the outer part of the inner shaft core can be processed into a stepped shaft to adapt to different coating machine types; in addition, in order to enhance the corrosion resistance and the wear resistance of the coating roller, the surfaces of the inner shaft core 1 and the outer roller body 2 can be subjected to chromium plating process treatment, so that the range of types of the coating liquid which can be contacted with the coating liquid is expanded, and the service life of the coating liquid is prolonged.

Referring to fig. 2 specifically, the shape of the dot holes 3 formed in the surface of the outer roller body 2 is one or more of an inverted pyramid shape, a hexagonal honeycomb shape, a regular dot shape, and a truncated pyramid shape, the gaps of the dot holes 3 are used for temporarily storing the coating liquid and transferring the coating liquid to the surface of the substrate to be coated with the coating liquid, the hole size of the dot holes 3 is used for controlling the amount of the coating liquid that can be transferred by the outer roller body 2, if a uniform coating thickness of the whole width is desired, it is necessary to ensure that the distribution of the dot holes 3 on the whole outer roller body 2 is also uniform and accurate, the openings of the dot holes 3 are slightly inclined toward the side where the polishing area 2b is located, when the coating roller rotates at a high speed in the coating process, the coating liquid such as glue flows along only one side of the reticulate, and the side is the side close to the side where the polishing area 2b of the rotating motor is located.

The working principle is as follows: in the coating process implemented by adopting the coating roller with the single-side polishing, the outer roller body 2 is screwed on a coating machine through the inner shaft core 1, the rotating motor drives the outer roller body 2 to rotate through the speed changing device, the coating liquid is taken up and temporarily stored in holes of the dot holes 3 of the mesh pattern area 2a on the outer roller body 2, then when the outer roller body 2 is in contact with the surface of a substrate to be coated with the coating liquid, the accumulated liquid in the holes is transferred to the coating substrate at a certain ratio, in the process, part of the overflowing redundant coating liquid flows along one side of the mesh pattern, and the polishing area 2b on one side, close to the rotating motor, of the outer roller body 2 effectively avoids the phenomenon that the edge coating liquid is stuck to the roller due to the characteristic that the surface of the polishing area is relatively smooth, so that the original device for controlling the bridge section can be removed during coating.

The coating roller with the single-side polishing function is used, the problem that liquid accumulation at the edge of a bridge section is too thick due to control of the bridge section in the coating process is solved, at present, when the traditional anilox roller is used for coating, if the whole surface coating is carried out, the liquid accumulation at the edge can be caused, the coating liquid is adhered to a roller body, so that the coating liquid is adhered to the back surface of a base material without the need of the liquid accumulation, and the bridge section is required to be controlled at one side of the liquid accumulation of the coating roller; in the coating process, the coating roller rotates at a high speed, so that coating liquid such as glue and the like is prevented from being accumulated along the grain flow direction side of the anilox roller, a liquid blocking strip is arranged, a plurality of millimeters of non-coating liquid is arranged on the edge of a base material at one end provided with the liquid blocking strip, and the part without the coating liquid is a bridge section; when the coating type back plate is produced, when the coating liquid controls the bridge section in the coating process, the bridge section is easy to accumulate too much liquid, so that the edge of the material is too thick, and the edge is warped if the bridge section cannot be completely cut off in the rear section cutting process. The coating roller with the single-side polishing function can remove the bridge section, and effectively solves the problem of excessive edge effusion.

While the utility model has been described with reference to specific preferred embodiments, it will be understood by those skilled in the art that various changes, modifications and additions may be made without departing from the spirit and scope of the utility model.
